QNAP Systems, Inc. (QNAP), a leading storage, network and computing solution provider, today officially released QTS 4.3.5. Designed to unleash the full advantages of SSDs to meet the demands of the high-speed networking era, QTS 4.3.5 marks a highly-anticipated milestone for NAS operating systems. Alongside the software-defined network architecture and additional functionality, the feature-rich QTS 4.3.5 delivers an exceptional performance-driven and streamlined user experience.

“During the QTS 4.3.5 beta testing, we gathered valuable user feedback that helped us put the finishing touches to the official release,” said Cherry Chen, Product Manager of QNAP. QTS 4.3.5 now packs numerous detailed improvements and enhancement, including, but not limited to, the following:

Restoring from remotely-stored snapshots: Snapshot restoration from a remote snapshot replica can now be directly written back to the local NAS through the network without manually restoring all folders and files at the backup destination then copying them back to local NAS. This saves time and effort by streamlining operations.

Flexible volume configuration and conversion: Volumes can now be converted between thin- and thick-provisioning, providing maximum flexibility of storage space allocation. Volumes sizes can be shrunk as well, ensuring the NAS can adapt to changing needs of storage allocation.

Advanced support for SmartNICs: QTS now supports powerful features that are built into advanced network interface controllers (NICs), such as the Mellanox® ConnectX®-4 for iSCSI Extensions for RDMA (iSER).

The brand-new Notification Center consolidates system logs and notifications for all NAS apps into a single app with flexible rule settings, facilitating smooth and easy NAS managements. There are also more notification methods, including email, SMS, instant message, and push notification.

Security Counselor – A security portal for QNAP NAS

Security Counselor checks for weaknesses and offers recommendations to enhance NAS security and to protect data against multiple attack methods. It also integrates anti-virus and anti-malware scanning software to ensure the complete protection of QNAP NAS.

Features and functionality are subject to change and may not be available for all QNAP NAS models.
